✦ Synopsis

Various recent publications on the evaluation of the Voigt function generally suffer major mathematical and computational flaws. It is important to draw attention to these flaws, particularly as they engendered physically incorrect results that strongly contradict the basic knowledge and acquaintance of the spectral line profile. We comment here on a computational error in the evaluation of the Voigt function, which led to physically incorrect results for the Voigt line profile [Asfaw A. A fast method of modeling spectral lines. JQSRT 2001;70:129-137].

P. Fischer and J. Mullen [3] have recently proposed a stabilization technique for the solution of the unsteady Navier-Stokes equations with the spectral element method. It is based on interpolations in physical space: Given the values of a function u on a Gauss-Lobatto-Legendre (GLL) mesh with (N +

When performing line-by-line simulations of atmospheric high-resolution infrared spectra, a large portion of the computation time is spent in the calculation of the absorptions by the far wings of the absorption lines. For applications in which one is interested mainly in evaluating the effective ab
